Detailed Product Description: | Tongchuan secondary pressurized water supply equipment, Tongchuan secondary pressurized water supply equipment design choice points in the world really do not know how many people can become successful, because of the rare times gently let caused obscurity. - Guy de Maupassant Tongchuan Water Supply Equipment Co., Ltd. in the beam parallel multi-pump constant pressure water supply equipment, the design can be achieved under constant conditions for each frequency of the pump efficiency constant (due to conditions unchanged), and make it in high efficiency zone work, the frequency of the pump flow is changing, its working efficiency with the flow and change. Because the use of multiple parallel constant pressure water pump, pump-power reduction, which can reduce energy consumption and more pumps in parallel constant pressure water supply systems, improve energy efficiency status. Tongchuan secondary pressurized water supply equipment installation: 1, the installation piping reasonable amount shall not be allowed on the pump, the pump in order to avoid distortion, affecting the normal operation. Should be carefully examined two, before installing the pump abortion and whether the hard object, so as not to damage the impeller and the pump is running. 3, tighten the bolt, so as not to impact on pump performance vibration when starting. 4, in the inlet and outlet piping of the pump control valve installed in the vicinity of the pump outlet pressure gauge is installed to control the pump operation within the rated operating conditions, to ensure the normal use of the pump. 5, the discharge pipe loaded check valve should be installed outside the gate. 6, the installation of the pump installation is divided into rigid and flexible coupling connection installed. Tongchuan secondary pressurized water supply equipment design choice points: 1) pressure tank manufacturing unit should hold a pressure vessel manufacturing license or registration book, and have a sound quality management system and the system. Purchased fittings 2) the device must have a product and by the admission certificate after passing inspection before use. Components pressure tank equipment, water pumps, electrical components, etc., should be inspected before assembly after use. Using on-site assembly of equipment, on-site inspection and machine performance. 3) should hold production licenses issued by the relevant departments. 4) use of the term products, respond to the following requests: equipment components, equipment classification, equipment, work pressure, equipment design flow, pressure tank specification number, equipment, materials, hygiene requirements. 5) the overall structure of the device, water pipeline, gas line and electrical wiring layout should be reasonable and should leave space for ease of installation and maintenance operations. Pipeline 6) equipment shall set the safety valve, the opening pressure of not more than 1.1 times the maximum working pressure. 7) Fire and Life (production) shared device must have a separate fire outlet. Condition: suitable for direct extraction of water for municipal fire water supply pipe network occasions; suitable for life, fire combination of a water supply equipment occasions; suitable for fire fighting water pressure for fire inspection and other special requirements of the occasion; can improve the practical effects of fire water. Tongchuan secondary pressurized water supply equipment, the main function of an automatic multi-pump unit soft-start, frequency operation and the entire procedure to stop frequency to 2, according to changes in water, become a multiple pump start and stop . 3, LED pressure setpoint and the actual pressure value display. 4, LED frequency indication, frequency exception indicates that motor failure conditions. 5, protection features: undervoltage protection, overvoltage protection, overload protection, short circuit protection, stall prevention, to prevent burning and other functions. Tongchuan secondary pressurized water supply equipment Scope 1, with pools of high-rise buildings, hotels, schools, residential area towns, enterprises, new rural construction domestic water in rural areas. 2, factories, industrial and mining life or production water. 3, all kinds of water plants, water supply stations, sewage waste water plant, agricultural irrigation and drainage stations, water supply and drainage. 4, high-rise, residential, centralized hot water supply enterprises. 5, production and life of the cooling water, circulating water pressure. 6, oil pipelines, oil depots, petrol stations, etc. constant pressure oil. Tongchuan secondary pressurized water supply equipment works equipment put into use, the water pipe network of water into the water tank, the tank eliminator exclude air from the vacuum, to be filled with water, remove the vacuum automatically turns off. When the water pipe network water pressure to meet the requirements, the system consists of a bypass valve from the users directly to the water supply pipe network; when the water pipe network pressure can not meet the water demand, the system pressure gauge feedback signal from the remote to the inverter controller, pump operation and automatically adjust the speed according to the size of water pressure water supply, if the operation of the pump frequency to achieve speed, then start another pump frequency operation. Pump water, if the water pipe network is greater than the pump flow system to maintain normal supply; water peak, if the water pipe network is less than the pump flow rate, water tank of water as a supplemental source of water supply still normal at this time, vacuum to eliminate air from entering the water tank, the tank vacuum destroyed, to ensure that the water pipe network does not produce negative pressure, the water peak, the water supply system has returned to normal state. When the water pipe network without water, causing the water tank level continues to drop, the level detector will signal back to the inverter controller, the pump automatically shut down to protect the water pump, water tank can store and release energy, avoiding the frequent pump starts. Drive in Tongchuan secondary pressurized water supply equipment applications 1, frequency control and analysis of the characteristics of the user how much water is constantly changing, so it occurs when the water supply is insufficient or excess supply situation. The imbalance between supply water and concentrated reflection on the water pressure, that much water and less water, the pressure is low; less water and more water, the pressure is great. Maintaining a constant water pressure, can maintain the balance between the water supply and water supply that is also more water for a long time, the water supply is small are small, thereby improving the quality of the water supply. Tongchuan secondary pressurized water supply equipment for certain industries or particular user is very important. For example, in some of the production process, if the water supply for any reason without water pressure is insufficient or short-term, may affect product quality, serious when the product scrap and equipment damage. Another example is when the fire broke out, or if water pressure or water supply shortage, not rapid fire, may cause significant economic losses and casualties. So, some of the water district uses Tongchuan secondary pressurized water supply equipment, with great economic and social significance. |
